After upgrade to PHP 7 the logs almost choked on this kind of errors:

`PHP Warning: Declaration of Example::do($a, $b, $c) should be compatible with ParentOfExample::do($c = null) in Example.php on line 22548`

How do I silence these and only these errors in PHP 7?

- Before PHP 7 they were `E_STRICT` type of warnings [which could be easily dealt with](https://stackoverflow.com/questions/1248952/php-5-disable-strict-standards-error). Now they&#39;re just plain old warnings. Since I **do** want to know about other warnings, I can&#39;t just turn off all warnings altogether.

- I don&#39;t have a mental capacity to rewrite these legacy APIs not even mentioning all the software that uses them. Guess what, nobody&#39;s going to pay for that too. Neither I develop them in the first place so I&#39;m not the one for blame. (Unit tests? Not in the fashion ten years ago.) 

- I would like to avoid [any trickery][1] with `func_get_args` and similar as much as possible.

- Not really I want to downgrade to PHP 5.

- I still want to know about other errors and warnings.

Is there a clean and nice way to accomplish this?
